 Setting TIM2_SMCTRL.TSEL = '000' to connect TIM1 trigger output to TIM2.
 Setting TIM2_SMCTRL.SMSEL= '101' to set TIM2 to gated mode.
 Setting TIM2_CTRL1.CNTEN= '1' to start TIM2.
 Setting TIM1_CTRL1.CNTEN= '1' to start TIM1.
Note: The TIM2 clock is not synchronized with the TIM1 clock, this mode only affects the TIM2 counter enable signal.

In the next example, Gated TIM2 with enable signal of TIM1, Setting TIM1.CTRL1.CNTEN = '0' to stop TIM1. TIM2
counts on the divided internal clock only when TIM1 is enable. Both counters are clocked based on CK_INT via a

The configuration steps are shown as below

Setting TIM1_CTRL2.MMSEL=' 001' to use the enable signal of TIM1 as trigger output
 Setting TIM2_SMCTRL.TSEL = '000' to configure TIM2 to get the trigger input from TIM1
 Setting TIM2_SMCTRL.SMSEL = '101' to configure TIM2 in gated mode.
 Setting TIM2_CTRL1.CNTEN= '1' to start TIM2.
 Setting TIM1_CTRL1.CNTEN= '1' to start TIM1.
 Setting TIM1_CTRL1.CNTEN= '0' to stop TIM1.
